Ok, so this has happened twice so now I'm worried. When I'm driving, my digital dash will flicker off, the gas needle will jump to full, and the engine will start to lose power almost to the point of turning off... TAP the digital cluster, lights come back on and the car goes back to running. Any ideas? PS...is a ECM and PCM the same thing? And can I trust products from RMSautoparts.com?
